Application filed September 3, 1914. Serial in. 8503s T aZZ whom itmay-concern.

Be it known that 1, E3111, JAGENBERG, a subject of the German Emperor,and resident of 107 Himmelgeisterstrasse, Dusseldorf, Germany, haveinvented certain new and useful Improvements in and Relating toBox-Making Machines, of which the following is a statement.

The present invention relates to a box making machine as described inthe United States Patent 608,201.

The inventionhas been exemplified in the accompanying drawing.

Figure 1 is a side elevation. Fig. 2 is a plan, and Fig. 3 is a crosssection on the line AB. Figs. 4; and 5 show the folding mechanism in twodiiferent operative positions. Fig. 1 isan end view'of the paper stripfeed locking means and Fig.1 a side view thereof.

Between the walls 1 a pile of-pasteboard strips 2 lieson rubber bands 3,which are laid around rollers 4c, 5. To the roller at is fitted atoothed wheel 6 and also loosely thereon a sprocket 7 and attachedthereto a clutch member 8. Toward this clutch member 8 the clutchmember-.9 displaceable but 'not rotatable on shaft 4 is pressed by aspring 10. The sprocket 7 is driven by means of chain ,11, which travelsover a sprocket 12 on shaft 13. The shaft 1-3 is driven by means of achain drive H from shaft 15 and drives the rollers 16 by means of thechain drive 17 and the toothed wheels 18. In toothed wheel 6 engages apawl 19 which is fitted to a lever 20 the free end of which iscoupled'by a rod 21 with the lever 23 journaled on shaft 22. On theshaft 22 is also fitted a lever 24, the nose-shaped end of which 25 liesin the path of an abutment 27 fitted to the sprocket 26. The rod 21 hasa pin 28 which engages in a slot in the double-armed lever 29. The upperend of this lever is situated in front of a slot 30 in a shaft 31, towhich a feeler 32 is fitted which projects between the rollers 16.

When the abutment 27 strikes against the nose 25, the pawl 19 is liftedand the lever 29 is forced through the slot 30, .the shaft 31 turninguntil the lever 29 has penetrated the slot. Then-the shaft 31 turns backso that lever 29 cannot return. When the pawl 19 is lifted the shaft 4can revolve. The

' sprocket 7 which revolves continuously can 'ries with'it shaft 4 bymeans of theclutch members 8,, 9, so that the endless rubber lo v, I Lit lifts the feeler Thereby the snaft 51 is turned in such a manner,that the lever 29 can return through the slot 30. in eon-se quencethereof the levers and can rock backward whereby the pawl 19 is reengaand the shaft is is stopped, so that now L18 two clutch members grind oneach other. The rollers 16 puslr'wie pasteboard strip hetwecn the walls33, which are held suspended by the arms 34: and When thepasteboard'strip is here at rest, several bars 3% lower on it and pressit down onto the table 37. The bars are fitted to the shaft which isoperated by means of a lever 39, a rod i0 and a roller ll from a camdisk When the pasteboard strip lies flat on the table 37, the slides itfitted to the carriage d3 are advanced by means of the grooved disk sh")so that they against a longitudinal edge of the pasteboard strip andforce the latter sidewise, whereby it passes through a slot between thetable and the one wall 33 and reaches a bar 46. On this bar 4:6 lies astrip of paper 55, which is Wider than the pasteboard strip. This paperstrip unwinds from a roller 56 and is passed over gumining rollers 57and guide rollers 58 to the rail 46, on which it lies longitudinally buth it projects at the sides (Fig. at). Ont-L- this paper strip thesomewhat narrower pasteboard strip is advanced.

The bar at; is fitted to a vertically guided carriage 4:7 which israised and lowered by means of roller 48 and the cam disk Next to thebar -16 an angular bar or first folder 50 is fitted to a verticallyguided can riage 51, which is likewise raised and lowered by means of aroller 52 and a cam disk 53. When the pasteboard strip is lying on thebar =l6 the latter rises and, presses the pasteboard strip against astationary bar 54 (Fig. at). Tiien the angle bar rises and bends. up thefree edge of the paper strip. Now abar or-second folder 59 advances andfolds the rising edges of the paper strip over onto the pasteboard strip(Fig. 5). The bar 59 is pivotally fitted by a broad arm 60 to the lever61, on which a roller is fit-ted, which rides on the cam disk The arm 69has two extensions 64;, to the ends of which a rod 65 is hinged, whichprojects through an eye on the lever 61, and on which I a spring .66 isfitted. .Thelower endo'f the band, a pair of feed rollers, a feelerinterrod 65 bears on a cam disk 67. First the bar 46.'

' pasteboard strip and hold the same during bar 59 is, swung forward bymeans of lever 61 and cam disk 63, wherebythe edge-of the paper strip isfolded over. Then, at its further advance the'bar is lowered by means ofrod 65 and the cam disk 67, so that it presses the paper strip againstthe upper side of the pasteboard strip (Fig. 5). When the bar-539- hasreceded and the bar .46 has been lowered a little, a gripper 68advances,

grips the front edge of the pasteboardstrip and it with the paper stripfrom the paper strip is thereby unwound from the roii 5'6. 1 Then ashears 69 closes by its blades being operated by the rods 70 and thelever *4" On the bar '54 a pin 72 is fitted vertically displaceable,which is depressed by a spring 73. This pin is' held in lifted positionby the upper blade of the shears, but when this blade is lowered forcutting,"also the pin 72 will sink onto the the cutting operation. Thepasteboard strip on which the paper strip has been pasted is then takenby the gripper to the known box.

I claim:

1., In :1 box-making machine, a paper-strip feeding band, means foroperating said posed between said rollers, means actuated by thefeeler'. for arresting the band operating means, a table adapted toreceive the paper strip, a bar, a slide for shifting the strip from thetable to the bar, means" for feeding a second paper strip to the bar,

means for mming said second strip, and means for oldmg said second striparound one edge of the first named strip.

2.- In a box-making machine, a paper strip feeding band, means foractuating said band, walls between which the strip is adapted to'enter,a bar, means for advancing said strip onto said bar, means for feeding asecond paper strip to the bar, means for gumniing said second strip,means for lifting the bar, avertically movable folderlocated 'sidewiseof the barfand adapted to turn fsecond strip, means for folding thesecond strip around one edge of the first named strip to form a compoundstrip, grippers for drawing the compound strip off said bar,
